Abstract : Mangifera indica, a commonly used plant in ayurvedic medicine and its parts have been used for various purposes. In India, seed kernels are used for the treatment of diarrhoea, dysentery, ulcer etc. Present study deals with pharmacognostic and phytochemical evaluation of Mangifera indica seed kernel (MISK) and to establish its pharmacognostical and phytochemical standards. It was reported that the quality of raw drug under study provides pharmacognostical standard for the drug seed kernel. Results of MISK powder yielded 1.72% total ash; acid insoluble ash not more than 0.05%, water soluble ash not more than 0.95%, hexane extractive value not more than 5.61%, chloroform extractive value not more than 1.34%, ethylacetate extractive value not more than 1.4%, ethanol extractive value not more than 18% & water extractive value not more than 21%. Major chemical constituents of water and alcoholic extracts were alkaloids, flavanoids, tannins & phenols. Microbial assay indicated that total microbial load and other microorganisms were within the limits of ayurvedic pharmacopoeia. Pharmacognostical and phytochemical parameters determined in the present work can serve as major criteria for identity, quality and purity of a crude drug and extracts.
